00WU43Z is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together procedures for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on the primary procedure being performed. Once a patient is assigned a particular group, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care associated with a particular procedure. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The procedure code 00WU43Z is present in the following groups for version MS-DRG V42.0 applicable from 10/01/2024 through 09/30/2025.

What is ICD-10-PCS?

The ICD-10 Procedure Coding System (ICD-10-PCS) is a catalog of procedural codes used by medical professionals for hospital inpatient healthcare settings. The Centers for Medicare and Medicaid Services (CMS) maintain the catalog in the U.S. releasing yearly updates. The 2025 ICD-10-PCS codes are to be used for discharges occurring from October 1, 2024 through September 30, 2025.

Each ICD-10-PCS code has a structure of seven alphanumeric characters and contains no decimals. The first character defines the major "section". Depending on the "section" the second through seventh characters mean different things.
